sf6 gas Gas Analysis - Qrometric

For Sulfr hexafluoride filled gas compartments, gaz sf6 in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).Get price

The Problem with Humidity in Sulfr hexafluoride Gas-Insulated Systems

As the gas temperature increases, more water molecules pass to the gas until a new equilibrium is reached. (left) A certain gas can absorb 10 molecules of water at 86°F (30°C). If at 77°F (25°C) it can absorb 7 molecules (center), the remaining 3 molecules will form a water layer at the bottom of the container.Get price
